I'm not on that box right now, but I did note that inherit permissions was 
checked on everything.  I guess that's not good <g>.

By next version, I presume you are saying - not what you get right now by 
running setup.exe, right?

Let's see if I understand:

1.  My current version of Cygwin is going to have problems on Windows 2000 
no matter what.  I can turn off permission inheritance on c:\cygwin and 
subdirectories, but anything created via cygwin will have permission 
inheritance turned on and will thus be a mangled mishmash.  I presume this 
is a W2K issue that does not occur on NT.

2.  The next Cygwin version will work right for objects created under 
Cygwin, but existing directories will be wrong unless I fix them manually. 
 I presume the to do list includes modifying setup at some point to omit 
permission inheritance when installing files/directories.
